I have the following visualization of graph produced by ELK layered algorithm:

index.php/fa/38714/0/

index.php/fa/38714/0/

(red lines I have drawn in Paint just to mark the layers of the layout)

What i am trying to achieve is to make this graph visually more compact. Is it possible to make ELK build layers over child nodes and consider parent nodes as visual clusters only? Something like this:

index.php/fa/38715/0/

index.php/fa/38715/0/

I would be grateful for any ideas or workarounds

You could try setting the post compaction strategy (https://www.eclipse.org/elk/reference/options/org-eclipse-elk-layered-compaction-postcompaction-strategy.html) to EDGE_LENGTH. That is not exactly what you sketched, but might satisfy your needs.
